GEORGE GODDU, F WINCHESTER, MASSACHUSETTS, ASSIGNO TO NITED SHOE MA-CHINERY CORPORATION, OF PATERSON, NEXV JERSEY, A CORPORATION OF NEWJERSEY LASTING MACHINE Application led September 28, 1926, Serial No.138,300, and in Great' Britain July 15, 1926.

' inwardly over the insole and fastening it by staples in thesamegeneral manner as disclosed in Letters Patent No. 1,731,853, grantedupon an earlier application of mine on Oct. l5, 1929. It will berecognized. however, that in various novel and useful aspects theinvention is not limited to machines of the particular type illustrated.

One object of the invention is to provide means for operating anupper-pulling gripper in such manner as practically to insure that thegripper jaws will, under all i' conditions, properly grip the uppermaterials. In the use of machines for lasting different portions of ashoe successively the margin of the upper materials is frequentlyinclined more or less inwardly over the insole, so that the liningespecially may lie close to the bottom of the insole where there isdanger that the gripper jaws may not properly seize it. The presentinvention pro-y vides a construction such that the gripper, beforemoving outwardly over the shoe t0- ward the edge of the insole intoposition to grip the upper materials, is moved into close relation tothe bottom face of the insole, so that in moving outwardly toward theedge the gripper jaws will properly receive between them the differentlayers of upper materials, including the lining. As herein illustratedespecially in relation to welt shoe work, the gripper is moved firstinto a position where one jaw may be closer to the plane of the insolethan the top of the insole lip or rib, and is then moved outwardly andaway from said plane to insure clearing the rib, with a further movementoutwardly and toward said plane outside of the rib.

ln the pulling ot the upper heightwise of the last it is desirable toavoid contart of the upper with the edge of the insole, such as mightresult in the raising of the margin of the insole from the bottom ofthe'last. To

this end, the machine herein shown is further provided With means whichis operative independently of the updraw movement of the vgripper toimpart to the grippermovement in a direction to pull the upper out-Wardly from the side of the last and the edge of the the insole. Thegripper thus receives a distinct outdraw movement in addition to itsupdraw movement, thereby insuring that the upper will clear the edge ofthe insole irrespective of such variation as there may be in theposition in which the operator presents the shoe.

ln accordance with a further feature,l the gripper herein shown is somounted that in its overdrawing movement, whereby it pulls the margin ofthe upper inwardly over the insole, it swings about an axis so arrangedthat the gripper jaws approach the bottom face of the insole. It isdesirable that the gripper maintain its hold on the upper until theupper has been firmly pressed against the insole by the over-layingmeans, especially in an organization such as illustrated in which theoverlaying member moves in a direction inclined toward the plane of theinsole; and the overdrawing movement of the gripper jaws thus takingplace in such manner as to approach the plane of the insole facilitatesthe overlaying operation without relaxingthe tension under which theupper is held by the gripper.

Still other features of the invention, relating especially to theupper-pulling means, are to be recognized in a novel organization ofgripper-operating and controlling mechanism, having particularly in Viewa simple, compact and conveniently accessible arrangement of parts. Forimparting to the gripper its npdraw movement there is provi-ded atwo-part npdraw lever of novel construction, with a spring aording ayielding connection between the two parts of the lever. In theconstruction shown the spring extends forwardly in a substantiallyhorizontal direction toward the operators working position and isprovided at its front end with a tension-adjusting nut which theoperator may conveniently roach in hisl working position.

The shaft58 is connected by beveled gearing 82 (Fig. 15) to a horizontal shaft 64on one end ot which is secured an internal gear Wheel 88 (Fig. 18)engaged by a@ pinion 68 on a drivingshaft which, in the constructionshown, is operated by an electric motor 72 mounted on the base 30. ltwill thus be seen that the shaft 611 is rotated in the same direction asthe shaft 70, but at reduced speed by reason of the relation between thesize of the pinion G8 and that of gear 66.

(lo-operating With the clutch member 50, (Fig. 4) of the continuouslyrunning gear Wheel 18 is a clutch member 74: formed as a llange on aclutch drum 76 which is mounted for sliding movement lengthwise of theshalt 42. The clutch drum 76 is coupled to the shatt 12 by means of aplurality of pins 7 8 which are fast in a disk 80 that is keyed to theshaft, the pins extending through holes in the drum 7G to permit thesliding movement. of the latter alongthe shaft. Springs 82 on the pinsT8 act, when permitted, to move the clutch drum 78 toward the right(Fig. 4) and thus to disconnect the clutch member 7 f1 from the member50. For moving the clutch drum 76 in the opposite direction to connectthe clutch members and thus to start the operative movement of the camshaft 42, there is provided a Wedge member 81- slidably mounted betweentl o compensate tor Wear oit r ne clutch drum and an abutment 88 last onthe shaft 42. The Wedge member is pivotally connected at 88 (Fig. 5) toan arm 90 which is carried by a lever 92 curved about the clutch andpivoted at 94 on the head rlhe arm 90 is pivoted at 98 on the lever 92for purposes of adjustment, and is held in adjusted position by means ofopposite set screws 08 arranged to engage a projection 100 on thelever92. f

Carried also by the. lever 02 is a brake shoe 102 arranged to engage aflange 101 on the clutch drum 70, the bralrc shoe'beino' pivotallymounted in a yoke-shaped portion ot the lever 02 on an eccentric portion106 ot a shaft 108v alone; which it slides vvhen the clutch drum ismoved lengthwise of the shait llv means of a member 110 tast on theshait 108 the eccentric 100 may be adjusted to position the brake shoein proper relation lo the Flange 101.1he member 110 beine` slotted toreceive a clamping screw 112 vvhcrebv it is held in adjusted position.Mounted b v nica s ol a spring arm 111 on one end of the breite shoe 102is a lubricating member 11G -comprising a piece et telt saturated withoil and in engagement with the flange 10st.

Connected to one end ot the lever 92 is a spring 118 which acts, whenpermitted, to swing the lever in the direction to pull the Wedge member841 outwardly and simultaneously to apply the brake shoe 102 to theflange 10e for bringing the cani'shatt 42 to a stop. For swineing thelever 92 against the resist ance ot tlie spring 1.18 to release thebrake and simultaneously to set the clutch for starting the operationoit the shaft 42, there is provided a treadle 120 which is tast on arock shaft 122 (Fig. 16) provided with an arm 124e connected by means ofa rod 126 to an arm 128 (Figs. 5 and 6) loosely mounted on a rock-shaft180, the arm 128 being forked at one end to provide a pair of spacedmembers 182 bearing on the rock-shaft. Between the members 182 there isalso mounted loosely on the rock-shaft 130 an arm 184C connected by alink 138- to the lever 92. Mounted in a lug' 138 projecting from the arm1341 underneath a portion of the arm 128 is a screnT 140 the upper endot which is arranged to be engaged by a portion of the arm 128 to impartoperative movement to the arm 18-1 and the link 136 when the treadle 120is depressed. The ar'm 128 andthe treadle 120 are held normally in idleposition by a. spring 1li-2, the idle position of the arm beingdetermined by a screw 111 which is carried by an ear on the arm and isarranged to engage an abutment 146 on the head of the machine. The partsare so arranged that, When the arm 128 is in its idle position, thatportion of the arm which cngages the screw 1110 on the arm 181 is spacedabove the upper end of the screw, so as to prevent the arm 128 fromlimiting, under any conditions of Wear, the bralre-applyindr movementot' the lever 92.

ln order to prevent the shalt 42 from coming to a stop at any pointexcept at the end of the cycle of operations, the lever 02 carries aroll M8 which initially is positioned in a depression 150 in the clutchdrum 78 but, when the operative movement of the shaft 42 is started, isengaged by a peripheral tace 152 on the clutch drum to prevent the lever92 from being swung back into position to stop the machine until thedepression 150 again arrives in a position opposite the roll 118. rlheroll 148 is mounted on a holder 154i which is adjustable in the lever bymeans oil. a screw 156, a clamp screw 158 beingfurther provided forsecuring the holder in adjusted position.

.ls hercinbefore explained, the cam wheel 40 for operating' tlu`2c'rij'ipcr docs not necessarily turn with the cani sha'lit 42, so thatthe machine may. if desired, be used only as a staplingr machine Withoutpulling the upper; and the machine will be so used it the treadle 120alone is depressed. lidor connecting` the cam Wheel 1G to the shalt 12there is provided a separate clutch controlled by anothernecting the camwheel 46 to the shaft 42 is herein shown as a pin clutch 4, 7 and 8),the cam wheel having a lateral extension 162 in which is slidablymounted a clutch pin 164 arranged to be moved into and out of an opening168 provided in a disk 170 which is fast on the shaft 142, a spring 166being provided for moving the pin into the opening upon depression ofthe trcadle 160. The clutch pin 164 is controlled by a treadle-opcratedwedge member 172 which lies in a groove 174 (Fig. 4) in the extension162 and is arranged to engage a lug 176 projecting from the clutch pintirough a slot in the extension. rl`he wedge member 172 is fast on anarm 178 secured to the rock-shaft 130, and mounted also on the arm 178is a resilient stop member 180 arranged to be engaged by the lug 176 onthe pin 164 to insure against overrunning of the cam wheel 46 when it isdisconnected from the disk 170.

The rock-shaft 130 is connected to the treadle 160 by means including anarm 182 (Figs. and 6) which is fast on the rockshaft and upon whichthere is pivoted a depending yoke member 184 connected by a rod 186 toan arm 188 (Fig. 16) fast on a rockshaft 190 on which the treadle 160 issecured. Provision is afforded for limited movement of the rod 186relatively to the yoke member 184 when the treadle 160 is depressed, therod beine slidably mounted in the yoke member and raving fast thereon ablock 192 which is arranged to engage a shoulder 194 on the yoke memberand thus to impart movement to the latter after a limited amount ofmovement of the treadle. The amount of lost-motion thus provided for issubstantially the same as that between the arm 128 and the screw 140, sothat both clutches will be actuated substantially simultaneously. Afurther reason for the lost-motion between the rod 186 and the yokemember 184 is to relieve the arm 182 of the weight of the treadle 160.For returning the rock-shaft 130 and the wedge member 172 into positionto disconnect the cani wheel 46 from the shaft 42 when the treadle 160is released, there is connected to the arm 182 a spring 196. It will beevident that, by reason of the relation between the treadles 120 and160, the return ot the treadle 160 to its idle position is effected i hvthe same spring 142 which returns the treadle120.

From the Jforegoing description it will be understood that, if themachine is to be operated both to pull and to fasten the upper,

the treadle 160 is depressed, and that the machine will repeat its cyclefor lasting di'erent adjacent portions of the shoe in succession as longas the treadle is held depressed. In case it is desired to perform asingle upper-pulling and fastening operation in any location, theoperator depresses the treadle and immediately releases it, so that themachine will come to a stop at the end of a single cycle. If the machineis to be used only to fasten the upper, as may be desired, for example,adjacent to the heel and toe ends of the shoe, the operator depressesthe treadle 120 alone to cause the machine to drive one or more staplesdepending upon the length olf time that the treadle is held depressed.In the use of the machine in this manner the treadle will usually he socontrolled that the machine will come to a stop after driving eachstaple, thus allowing suflicient time for the operator to present inproper relation to the staple-driviner means each portion ot the shoewhere al staple is to be driven.

For pulling the upper to tension it and to draw it inwardly over theinsole, there is provided a gripper (Fig. 9) comprising a pair of jaws198 and 200, of which the jaw 198 is secured on the lower end of aholder 202 provided with a tubular shank portion 204. The shank 204 isslidably mounted in a sleeve member 206 pivoted on a stud 208 on thefront end of an over-draw rod 210 which is slidably mounted in bearingsformed in a bracket 212 on the head of the machine. At its upper end thetubular shank 204 is clamped in a holder 214 provided with a stud 216pivotally mounted in the front end of a lever 218 which is mounted on arock-shaft 220 on the head of the machine. Pivoted at 222 on the rearend of the lever 218 is another lever 224 provided with a roll 226engaged by a path cam 228 formed in one side of the cam wheel 46. Thelevers`218 and' 224 are so connected that they move normally as a unit,or as a single updraw lever, about the axis of the shaft 220 inimparting upper-pulling or updraw movement to the gripper, but haverelative movement against yielding resistance when the force of the pullon the upper exceeds a predetermined maximum. For this purpose there ispivoted at 230 on the lever 224 a forwardly extending rod 232 slidablymounted in a sleeve member 284 which is adjustably threaded in an upwardextension 236 of the lever 218. Between an enlarged head on the sleeve284 and a flange on the rod 282 there is mounted a fibre thrust washer288. Coiled about the rod 232 is an updraw spring 240 which bears at oneend against a cup-shaped washer 242 slidingly mounted on the sleeve 234and abutting normally against the front of the extension 286, the springbearing at its other end against a. nut 244 threaded on the rod 282within convenient reach ot the operator as he stands in front of themachine. It will thus be evident that when the force of the pull on theupper exceeds the tension of the spring 2467 the spring will yield,permitting the lever 224 to swing about its pivotal connection 222 withthe lever 218.

By turning the nut 244 the normal tension of the spring 240 may bevaried, in order to vary as desired the force of the pull on the upper,a wing nut 246 being provided for holding the nut 244 in adjustedposition. lt is sometimes desired to effect a quick adjustment of thetension of the updraiv spring, in order to vary the force of the pull in-changing from one kind of shoe to another or in operating on differentportions of the same shoe. chine is provided with means also withinconvenient reach of the operator in front of the machine for moving theWasher 242 forwardly to increase the tension of the spring, and Jforholding it in its forward position. This means comprises a lever 248pivoted at 250 on the lever 218 and having a yoke-shaped upper end (Fig.3) provided with pins 252 which bear on an outturned flange. formed onthe Washer 242. The lower end of the lever 248 is connected by a link254 to a crank pin 256 fast on a rock-shaft 258 carried by the lever218. The rock-shaft 258 is turned by means of a lever or arm 260 whichis fast thereon, and for limiting its turning movement the rock-shaftcarries a finger 262 arranged to engage a pin 264 on the lever 218, thearrangement being suoli that when the linger 262 is in engagement withthe pin 264 the crank pin 256 is on dead center, or slightly beyond deadcenter, so that the parts of the tension-adjusting mechanism areautomatically retained in adjusted position. The manner in which thismechanism is utilized to effect a quick adjustment of the-tension of theupdraW spring will be further evident from a comparision of the full anddotted line positions of the parts as indicated on Fig. 9.

The gripper jaw 200 is supported on the holder 202 by a link 266 and atits upper end is connected by a link 268 to a closing rod 270 slidiugly4mounted in the tubular shank 204. It will be understood that closingmovement of the jaw 200 toward the jaw 198 is effected by downwardmovement of the rod 270, the movement of the jaw being furthercontrolled by a cam member 272 on the holder 202 in substantially thesame manner as disclosed in the prior Letters Patent, the upper end ofthe j avv 200 having a nose portion 273 arranged to bear on the cammember and pressed toward said member by means of a spring plunger 274which is mounted in the jaw 200 and bears on a lug 276 projecting fromthe link 268. The cam member 272 is adjustable by means of a wedge 278controlled by a screw 280, and is held in adjusted position by a nut 282For this purpose the mathreaded on a rod 284 which projects from the cammember.

At its upper end the jaw-closing rod 270 is engaged by a rocker 286which is operated by'a thrust rod 288 slidingly mounted in a boss 290 onthe lever 218 and in an opening in the rock-shaft 22() which supportsand turns with the lever. Operative movement is imparted to the rod 288by a lever 292 pivoted at 294 on the head of the machine, this leverhaving mounted in an upward extension thereof a plunger 296 which abutsagainst the rear endo the rod 288. Adjustably threaded in the upwardextension of the lever 292 is a sleeve member 298 which provides abearing for one end of the plunger 296 and serves as an abutment for oneend of a spring 300 which bears at its other end upon a iange 302 formedon the plunger. The spring 300 is thus arranged to yield at the end ofthe closing movement of thejaw 200 and thereafter to hold the /jaw ineifective gripping engagement with the upper. Since the rod 288intersects thc axis of the updraw lever 218, and since its rear endwhich is engaged by the plunger 296 is close to said axis, the plunger296 opposes no substantial resistance to the updraw movement of thelever. The lever 292 is provided with a roll 304 engaged by a peripheralcam 306 on the cam Wheel 46 for imparting jaw-closing movement tothe rod270. leturn upward movement of the rod is etected by a spring 308 on thegripper, one end of which bears on a washer 310 on the upper end of thesleeve member 206 and the other end of which bears on a washer 312slidingly mounted on the shank 204, the Washer 312 engaging a pin 314carried by the rod 270 and extending through the rod and through slotsin the shank 204. To limit the upward movement of the rod 270 there isclamped onthe shank 204 a collar 316 in position to be engaged by thepin 314.

For operating the overdraw rod 210 there is provided a lever 318 whichis pivotally mounted on a rod 320 fast on the head of the machine and isforked at one end for sliding engagement with a block 322 pivoted on therod 210. At its vother end the lever 318 is provided with a roll 324engaged by a peripheral cam 326 on the cam Wheel 46. The movement of therod 210 in the direction to pull the upper inwardly over the insole isefected by a torsion spring 328 (Fi g. 3) one end of which engages a lugon the lever 318 while the other end engages one or another ot a seriesof teeth 330 formed on an adjusting member 332 328 holds the roll 324 inengagement with the cam 326, and that the cam acts positively on thelever 318 against the tension of the spring to move the gripperoutwardly toward the edge of the insole into position to grip the marginof the upper.

The movements of the gripper in the cycle of operations of the machineare illustrated in Figs. 19 to 22, inclusive. The shoe is positioned andguided by an anvil member or work rest 340, more particularlyhereinafter described, which engages the inner face of the insole rib,and the movement of the gri per into position to grip the mar 'n of t .eupper material is substantially 1n a path represented by the broken linea in Fig. 19.

i It will be seen that the gripper is first moved downwardly toward theinsole at the inner side of the rib in a direction substantiallyperpendicular to the bottom face of the insole, by the action of the cam228 on the lever 224, until the lower gripper jaw 198 is in a positionin which it may, as shown, be closer toV the bottom face or the plane ofthe insole than the top of the rib. The overdraw cam 326 then acts onthe lever 318 to swing the gripper outwardly toward the edge of theinsole about its pivotal connection 216 with the updraw lever 218; andby reason of the inclination of the shank 204 of the gripper,

A as illustrated in Fig. 9, this swinging movei stood that this path ofmovement of the gripper is such as to insure that the jaws will properlyreceive between them the diierent layers of the upper materials,including thel lining, in any position that the lining may assumerelatively to the rib of the insole.

At the end of the downward and outward movements of the gripper, thejaws are closed upon the upper by the cam 306, and thereafter thegripper receives its updraw movement to pull the upper. In this updrawmoveient the overdraw cam 326 acts to impart to the gripper a furtheroutward movement relatively to the side of the last, as illustrated inFig. 20, so that the gripper pulls the upper somewhat away from the edgeof the insole and the Vside of the last, to lessen the friction betweenthel upper and the last and to insure against bending the feather of theinsole upwardly from the bottom of the last. At the end of the updrawmovement the overdraw cam 326 permits the spring 328 to act to impartoverdraw movement to the gripper in time relation to the operation ofthe overlaying and fastening mechanism, hereinafter described. It willbe evident that this overdraw movement is a swinging movement about thepivotal connection 216, so that the gripper jaws have a component ofmovement downwardly toward the insole as well as inwardly from the edgeof the insole, thus facilitating the overlaying of the upper. The actionof the gripper, in relation to the overlaying and fastening means, willbe hereinafter further referred to in the description of the operationof the machine as a whole.

The overlaying and fastening mechanism, including means for formingstaples above the line of drive and for transferring them into alignmentwith the staple driver, is in many respects similar to the constructionshown and described in the prior Letters Patent. Secured on the head ofthe machine by clamping screws 342 (Fig. 2), and adjustable along aguideway on the head by means of a screw 344, is a bracket 346 which isso formed as to provide a forwardly and downwardly inclined guideway fora movable slide 348 (Fig. 10), this slide having mounted thereon theoverlaying means and also the staple transferring and driving mechanismsand a portion of the staple forming mechanism. For moving the slide 348along its guideway, there is formed in one side of the cam wheel 44 apath cam 349 (Fig. 2) which engages a roll 350 on the slide. i

Secured to the bracket 346 is a plate 351 (Fig. 11) which has dependingtherefrom a linger 352 shaped and arranged to serve as an inside formerfor the staple. Mounted also on the bracket 346, in fixed relation tothe inside former 352, is a wire-guiding nozzle 354 to which wire forforming the staples is fed by means hereinafter described, the wirebeing advanced until its end engages the head A of a stop screw 356 inthe bracket 346. The wire is thus fed forwardly over the upper surfaceof a block 358 which is mounted o n the front end of the movable slide348 and serves, as hereinafter described, as a member for laying theupper inwardly over the insole and as a nozzle for guiding the staple asit is driven. Secured to the block 358 are two guide members 360portions of which are spaced from the upper face of the block to providea guideway for the wire. The relation between the wire and thesedifferent parts will be more fully understood by reference to Fig. 13.

(lo-operating with the inside former 352 is an outside former comprisingtwo plates362 which are spaced apart and are provided with shouldersunder which the staple is formed and which serve thereafter as means forforcing the staple downwardly to transfer it into line with the driver(Figs. 12 and 13). The plates 362 are fast on a bar 364 which is mountedin a guideway on the slide 348 for movement indirections at right anglesto the directions of movement of the slide. It will be understood thatthe forming of the staple is effected by the forward movement of theslide 348, the Wire being first severed by a cutter 366. which iscarried by the slide and co-operates with the Wire-guiding nozzle-354 tocut the wire before the forming of the staple begins. Carried also bythe slide 348 is a plate 368 from the lower endfof which extends afinger 370 for pressing the cross-bary of the staple against the insideformer 352 at the end. of the forward movement of the slide to insurethat the cross-bar will be straight. The slide 348 is further providedwith a member or plate 372 which, at the end of the forward movement ofthe slide, arrives in position for one of its edges to align with theinside former 352 so as to serve as a guide for the staple as the latteris moved downwardly into alignment with the driver.

For imparting staple-transferring movement to the bar 364 which carriesthe outside former 362 there is provided a bell-crank lever 374 (Fig.2), one arm of which is adjustably connected by a link 376 to the bar364, and tbe other arm of which is provided with a roll 378 engaged by aperipheral caml 380 on the cam wheel 44. A spring 382 coiled about theaxis of the `lever 374 acts on the lever to impart staple-transferringmovement to the bar 364, and the cam acts positively to return the barand the outside former into staple-forming position. For limiting thetransferring movement of the bar 364 the slide 348 carries a stop screw384 (Fig. 10) which is engaged by a lug 386 on the bar, the screw 384being adjustable to cause the staple at the end of its transferringmovement to align properly with the driver.

The driver 388 is carried b a slide 390 mounted in a guideway forme in amember 392 fast on the slide 348. The end of the driver advances along aledge 394 (Fig. 14)

which receives and supports the staple at the end of the transferringmovement, `and in alignment with the upper surface of this ledge is astaple-guiding slot 306 formed in a cap 398 which is secured to theblock 358. For operating the driver slide 390 there is provided an arm400 which at its upper end is pivoted on a stud 402 on the shde 348 andat its lower end has a bearing in a recess formed in the slide 390. Thearm 400 is operated to impart staple-driving movement to the driver 388by a torsion spring 404 (Fig. l2), one end of which is connected to amember 406 which may be turned to adjust the tension of the spring andis held in adjusted position by a pin 408 arranged to enter any one of aseries of holes 410 formed in a member 412 fast on the stud 402. Tolimit the driving movement of the lever 400 there is provided a fibrewasher 414 which is adjustable by means of a screw 416 mounted 1n asplit bracket 418 -on the slide 348, a screw-420 with the slide.

being provided for effecting relative movement of the two parts of thesplit bracket to bind the screw 416 in adjusted position.

For swinging the arm 400 against the resistance of its spring 404 toretract the driver preparatory to the staple-driving operatlo'n, thereis pivoted at 422 on the head of the inachine (Figs. 2 and 10) a lever424 on which is pivotally mounted at 426 a latch 428 for engaging thelower end of a plate 430 on the .arm 400. A spring 432 connected at oneend to the latch 428 and at its other end to a pin 434 on the lever 424tends to hold the latch in position to engage the plate 430. It willthus be evident that when the slide 348 receives its forward movement,the arm 400 is held back by the latch 428, so that the driver 388 doesnot move forwardly For operating the latch 428 to release the arm 400for the staple-driving operation, the slide 348 carries an adjustablescrew 436 the head of which is arranged to engage and operate a finger438 projecting from the latch. The forward movement of the slide 348,however, does not carry the screw 436 far enough to act on the finger438, since it is necessary to allow time for the transferring of thestaple after the slide has arrived at the end of its forward movement.Release of the arm 400 is accordingly effected in response to a movementof the lever 424such as to cause the screw 436 to act on the finger 438to disconnect the latch 428 from the plate It is desirable that in Vthedriving of the staple its legs be guided in straightpiths as I theybegin to enter the work, so that they will be directed properly1 inrelation to the clinching means without stortion due to resistance ofthe work. For this purpose there is pivotally mounted in the nozzlemember 358 a guide member 445 having a portion correspending in width tothe distance between the legs of the staple and lying in the slot 396formed in the cap member 398, 4the guide member being held downwardly bymeans of Y a spring plunger 446. It will be understood that the guidemember 445 is housed within the staple nozzle where its action is notinterfered with by pressure of the upper thereon, and that afterperforming its function of guiding the legs of the staple the member islifted by engagement of the driver 388 therewith.

Vhen the staple is driven through the up per and the rib of the insoleits legs are clinched by engaging depressions 447 (Fig.

The means lor feeding the wire to form the staples is similar inconstruction to that shown and described in the prior Letters l3 atentrand need not be described herein in detail. lirietly stated, there is areel 468 (Fig. 3) tor the wire, mounted to turn on a pin 470, and fromthe reel the wire is led up over an idler pulley l and thence downwardlybetween leed rolls Tel and 76. From the feed rolls tte wire led througha tube flTS lo the wire- .gaidin'g nozzle S54. The feed roll Tet isoperi-ated by pawl and ratchet mechanism throiffh a link itil) and abell-crank lever 48,2 provided with a roll 49% engaged by a cam wheel 8Gon the camshaft. l2. ln order to stop the 'leed ol" the wire. ifdesired, there is providcv'l a linger which may turned by a ha ndle lilointo position to engage a lace :l on the lever and thus swing the leverinto such a position as to prevent it trom heing operated b v the camwheel In the use of the machine the operator preseuls a shoe with therib o l the insole in engagement with the work rest or anvil mem ber340, starting' usually at the lorepart ot the `shoe adjacent to thepreviously pulledover toe portion of the upper. and then depresses themain Starlingtreadle lill) and holds it depressed while moving the Shoelengthwise and turning it relatively to the member 340 as the contour ofthe side ot' the shoe varies along the ball and the shank, thus lastingthe shoe progressively from the toe end to the heel end. ln each cycleor operationsl the gripper is moved first substantially in the pathindicated by the line a (Fig. lll) into position to grip the margin ol1Vthe upper materials, as hereinbefore explained, and then receives itsupd raw movement combined with a further outward movement relativelv tothe side of the shoe, thus pullingl the upper somewhat away trom theside uit the last and the edge ol the insole, as illustrated in Fig. 20.The gripper then receives its overdrawinI"r movement. swinging about anaxis so located that the `gripper jaws approach the plane of the insolewhile moving inwardly over the bottom of the insole, without anyrelaxing' ot tha` tension of the updraw spring, During the overdrawinprmovement ot the gripper the overlaying' member 35S is moved toward the.Choc in a path inclined to the plane of the insole, engaging thetensioned upper tiret at a substantial distance above the ed ge of theinsole and then layingT or tucliirpr the upper into the angle betweenthe feather and the rib of the insole while the' upper is still held bythe gripper. At the end ot the inward movement of the member 358 themargin of the upper and the insole rib are clamped between this memberand 'the anvil member 340, which may yield to prevent excessive clampingpressure at any part of the shoe where an unusual thickness ot uppermaterials cneountered. After the up )er has been thus clamped againstthe rib ol the insole, or approximately at the time when the clampingtakes place. the gripper will preferably release its hold on the marginbefore the upper is fastened to the rib, since the clamping pressure issufficient to prevent any loss of tension.

In the forward movement of the overlaying member 358 a staple is formedin the manner hereinbefore explained, and after the member has arrivedat the end of its movement the staple is transferred into alignment withthe driver and is then driven through the upper and the insole rib andclinched by the member 3&0 while the upper and the rib are still clampedbetween this member and the overlaying member. Thereafter the parts arereturned to their starting positions llG preparatory to the beginning of.the next cyc e.

When it is desired to drive a staple without pulling the upper, forexample, at the rear end of the insole rib adjacent to the heel seat,the operator presents that part of the rib where the staple is to bedriven against the anvil 340, and then depresses the treadle 120 torender thek staple-forming and driving mechanism ,operative while thegripper lis idle, releasin the treadle immediately, so that the machlnewill come 'to a'stop at the end of a single cycle.

While the invention is herein shown as embodied in a machine designedespecially for welt work, it will lbe recognized that many of itsfeatures are not limtied to that type of Work, but are applicable tomachines for operatin on shoes of other types, and it is further to eunderstood that, except where the context requires a more limitedinterpretation, the term insole used in the appended claims is intendedto comprehend not only the insole of a welt or other type of shoe, butgenerally that part to which the upper is fastened in lasting, which insome types of shoes may be the outsole or the only sole with which theshoe is provided.

Novel features of the means herein disclosed for controlling the stapledriver are claimed in a divisional application, SerialI No. 402,495,filed on October 25, 1929.
